Hi Katherine,
Thanks for the response. I’m not sure what has caused this to happen. The artwork never gets direct sunlight and whilst is close to a heating vent doesn’t get direct contact and there is never a large change in temperatures. The resin is coming away from the lower corner not the top so I don’t think the vent would be contributing.
Is there anything you would suggest it reattach the resin back to the canvas to extend the lift of the artwork?
